Problems solved by technology

[0003] Most of the periodontal splints used clinically are covered with metal ligature wire or nylon wire and composite resin. The production of these periodontal splints requires manual plastic resin, which is time-consuming and labor-intensive, and most doctors do not Consider the shape of the resin on the side of the tooth and tongue, and the thickness of the resin is uneven, the surface is rough and the foreign body sensation is increased, and the outreach gap is not properly treated, resulting in the resin pressing the gingival papilla, which is not conducive to the patient's own plaque control

Embodiment 1

[0043] A kind of manufacture method of periodontal splint, with reference to figure 1 and figure 2 , proceed as follows:

[0044] 1): Use an oral scanner to scan the patient's mouth to obtain information about the patient's dentition;

[0045] 2): Design the shape of the periodontal splint according to the patient's dentition information;

[0046] 3): Make the designed periodontal splint by 3D printer;

[0047] 4): Polish the lingual side of the periodontal splint;

[0048] 5): Disinfect the periodontal splint;

[0049] When performing step 1), the 3shape oral scanner can be used to scan the patient's mouth to obtain the patient's dentition information;

[0050] Step 2) includes: 2-1: If the patient’s maxillary teeth are loose, use EXOCAD software to extract the surface information and arrangement information of the patient’s maxillary and lingual teeth; Arrangement information; 2-2: Use EXOCAD software to design the shape of the periodontal splint according to the surf...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that step 2) also includes: 2-3: Adding grid-shaped ribs on the tooth flanks of the periodontal splint (see image 3 ) to improve the bonding effect when using adhesives to bond periodontal splints to the patient's teeth.

Embodiment 3

[0062] A periodontal splint, manufactured by the manufacturing method disclosed in Example 1, including tooth flanks and lingual flanks, the tooth flanks are ergonomically curved surfaces adapted to the lingual flanks of the teeth, the lingual flanks are smooth surfaces, and the periodontal splint The thickness is 1.3-1.7mm and the width is 3-4mm.

[0063] The periodontal splint disclosed in this embodiment conforms to ergonomics and conforms to the shape of the adjacent tooth contact area, and the periodontal splint has high strength and small thickness; when the patient wears the periodontal splint disclosed in the embodiment, the foreign body sensation in the oral cavity is low , At the same time, the abduction gap of the patient's teeth will not be blocked by the periodontal splint, which is convenient for the patient to control the plaque by himself.

Abstract

The invention relates to a manufacturing method of a periodontal splint. The manufacturing method comprises the steps of 1) performing intraoral scanning on a patient by using an oral scanner to obtain the dentition information of the patient; 2) designing the shape of the periodontal splint according to the dentition information of the patient; 3) manufacturing and molding the designed periodontal splint through a 3D printer; 4) polishing the tongue side face of the periodontal splint; and 5) disinfecting the periodontal splint. The manufacturing method has the advantages that the manufactured and molded periodontal splint is convenient to use and beneficial for the patient to conduct plaque control; and the foreign body sensation of the oral cavity of the patient is low.

Description

technical field [0001] The invention relates to the technical field of loose teeth fixing in the treatment of periodontitis, in particular to a periodontal splint and a manufacturing method thereof. Background technique [0002] Periodontitis is a chronic infectious disease with inflammation and destruction of periodontal supporting tissues, such as periodontal pocket formation, progressive attachment loss and alveolar bone resorption, and persistent periodontal tissue destruction will increase tooth looseness Degree, loosening of the lower anterior teeth is more common in patients with severe periodontitis. Clinically, for the treatment of loose teeth after controlling inflammation, periodontal splints are mainly used to fix loose teeth, so as to prevent loose teeth from affecting tooth function, aesthetics and patient comfort. [0003] Clinically used periodontal splints are mostly covered with metal ligature wire or nylon wire and composite resin. The manufacture of thes...
